2015 Chevrolet Impala Wheel Interchange

2015 Chevrolet Impala Wheel Interchange & Fitment Guide

Known OEM Fitment For 2015 Chevrolet Impala

The following specifications are known for certain 2015 Impala packages. Your trim may differ. Always confirm your exact stock sizes using the door-jamb tire placard, the owner’s manual, or by entering your VIN in an OEM parts catalog. If your numbers don’t match what’s below, use the on-page calculator to compare your setup.

Note: The wheel and tire sizes shown reflect different factory packages seen on the 2015 Impala. This is normal across trims. If your vehicle differs, verify your exact OEM size using the methods above and use the calculator on this page to compare any candidate wheel/tire.

How To Use The Wheel Interchange Calculator

• Set “Installed on (your vehicle)” to 2015 Chevrolet Impala.
• For “Wheels from (donor vehicle),” select a candidate vehicle or enter a custom setup.
• Use “Custom wheel size” to try different rim diameter, width, and offset. The calculator will show inner clearance, outer poke, and backspacing changes versus your Impala.
• Use “Custom tire size” (section width and aspect ratio). When you change rim diameter, the calculator updates total tire diameter in the comparison so you can keep overall diameter close to stock.
• Review the results: aim to avoid inner interference (strut, liner, brake caliper) and outer fender contact while keeping overall tire diameter within a small percentage of your stock size.
• If your OEM size is different from the table above, input your true stock numbers first for the most accurate comparison.

Fitment Checklist Before You Buy

• Bolt pattern: Must match 5x120.
• Center bore: Vehicle hub is 66.9 mm. If the wheel’s center bore is larger, use hub-centric rings sized to 66.9 mm. If smaller, the wheel will not fit.
• Thread/seat: Fasteners are M14 x 1.5. Confirm the correct seat type for your wheels (typically conical, but verify) and use matching lug nuts.
• Offset and backspacing: Compare with the calculator to confirm inner clearance to struts/springs and outer fender clearance. Avoid sudden, large changes in offset without verifying clearances.
• Brake clearance: Visually check that spoke and barrel clear the calipers. Some designs with the same offset may still hit large calipers.
• Tire load/speed rating: New tires must meet or exceed the ratings on your door-jamb placard.
• Overall diameter: Keep tire overall diameter close to your stock size to maintain speedometer accuracy and avoid rubbing. Use the calculator’s diameter readout.
• TPMS: Plan to transfer or replace sensors. Make sure the wheel’s valve stem hole and sensor mounting are compatible.
• Test fit: Spin the wheel by hand on the hub and turn steering from lock to lock. If possible, compress the suspension to check for contact under load.

Plus Sizing And Common Upgrades

Many Impala owners explore plus sizing for a sportier look and sharper response. The safest approach is to model changes with the calculator and keep clearances and diameter in check.

• Plus zero: Wider wheel/tire at the same diameter. Verify inner and outer clearance against your baseline offset and backspacing.
• Plus one or more: Increase rim diameter and select a tire with a shorter sidewall so overall diameter stays close to stock. The calculator updates total diameter as you change rim size.
• Known reference points: Some 2015 Impala trims came with 20 x 8.5 ET45 wheels. If you’re moving to 20-inch, compare your current tire diameter to a prospective tire and confirm clearance to suspension and fenders.
• Handling and ride: Lower profile tires can sharpen steering but may ride firmer and increase road noise. Inspect local road conditions when deciding.

If any value on your vehicle differs from the table (common across trims), enter your true OEM specs first, then iterate with the calculator to keep offset, backspacing, and diameter changes within safe margins.

Installation Tips

• Preparation: Park on level ground, chock wheels, and use jack stands under proper points. Clean the hub face so the new wheel mounts flush.
• Hub-centric rings: If your wheel bore is larger than 66.9 mm, install rings that reduce to 66.9 mm. Seat them fully in the wheel before mounting.
• Fasteners: Verify M14 x 1.5 thread and correct seat type. Start all lug nuts by hand to avoid cross-threading.
• Tightening: Snug in a star pattern, lower the vehicle, then torque in a star pattern to the factory specification for your trim. Do not oil or grease lug threads unless the service manual specifically instructs it.
• TPMS: Transfer sensors with new seals or install new sensors. Perform a relearn procedure after installation.
• Post-install: Test drive at low speed, listen for rubbing, and re-torque lug nuts after 50–100 miles.

Tools And Helpful Supplies

• 1/2 inch drive torque wrench
• M14x1.5 lug nuts (match your wheel’s seat type)
• GM TPMS relearn tool (EL-50448 compatible)
• Wire brush for hub cleaning

FAQs

• What is the bolt pattern for the 2015 Chevrolet Impala?

  It is 5x120 based on known OEM data for this model year. If your vehicle seems different, confirm using the door-jamb placard, owner’s manual, or an OEM parts lookup by VIN.

• What center bore do I need, and do I need hub-centric rings?

  The vehicle hub bore is 66.9 mm. If your wheel’s bore is larger than 66.9 mm, use hub-centric rings sized to 66.9 mm. If it is smaller, the wheel will not fit the hub.

• What is the correct thread size and lug style?

  The thread size is M14 x 1.5. Always match the lug nut seat to the wheel’s seat design and follow the torque specification in your owner’s manual or service information.

• Will 20-inch wheels fit my 2015 Impala?

  Some trims were equipped with 20 x 8.5 ET45 wheels. If your car came with a different size, use the calculator to compare overall tire diameter, offset/backspacing, and clearances. Verify brake caliper and fender clearance with a test fit.

• Can I use wheels from another vehicle?

  Possibly. Use the calculator’s “Wheels from (donor vehicle)” function to compare bolt pattern, center bore, offset/backspacing, and tire diameter. Only proceed if all safety checks pass.

• Do I need new TPMS sensors when changing wheels?

  You can transfer your existing sensors if compatible with the new wheels, or install new sensors. After installation, perform a TPMS relearn (a GM-compatible EL-50448 tool is commonly used) and verify no warning lights remain.

• What torque should I use on the lug nuts?

  Torque specifications can vary. Always follow the value in your owner’s manual or OEM service manual for your specific trim and fasteners.

• Is a staggered setup recommended on the Impala?

  Many owners prefer a square setup for rotation flexibility and predictable handling. If you choose staggered sizes, confirm clearances with the calculator and understand you will lose front-to-rear tire rotation.

If a value for your 2015 Chevrolet Impala is unknown or differs by trim, confirm it with your door-jamb placard, the owner’s manual, or an OEM parts lookup, and model the change using the calculator on wheelinterchange.com for a safe fit.
